SPECIFICATION forming part 0f Letters Patent NO. 500,954, dated July 4,1893.

Application filed August 27, 1892. Serial No. 444,253. (No model.)

To all whom t may concern,.-

Be it known thatI, WILLIAM RUNDQUIST, a

citizen of the UnitedStates, and a resident of Elgin, in the county ofKane and State of Illinois, have invented certain new and usefulImprovements in J eWel-Setting Machines for Watch-Jewels; and I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The nature of this invention consists in mechanism for forming a settingfor Watch jewels, introducing the jewel therein, and in finishing theljewel and setting, the several mechanisms being all arranged forautomatic and successive action.

With these ends in view, my invention consists of the novel combinationof devices, and in the peculiar construction and arrangement of parts,as will be hereinafter fully described and claimed.

In the accompanying drawingslz-Figure 1 is a side elevation of a machineconstructed in accordance with my invention. Fig. 2 is a plan View ofthe same. Fig. 3 is a longi tudinal vert-ical sectional View on theplane indicated by the dotted line -x of Fig. 2. Fig. 5 is a frontelevation. Fig. G is a detail View of the head of the cutting spindle.Fig. 7 is a similar View of thehead ofthe jewel burnisher. Figs.

8 and 9 are detail views of the truing head.

Fig. 10 is a detail' view of the cutter for truing the jewel setting;and Figs. ll, 12 and 13 are detail views of Vthe jewel feedingmechanism.

Like numerals of reference denote corresponding parts in all thefigures, referring to whichl designates abaseorsupporting bed which isfirmly secured ou top of a suitable work table or bench 2, and to thissupporting bed l is firmly and rigidly secured a tubular casing orcylinder 3. Within the cylinder or casing 3 is fitted a revolublecylindrical carrier 4 which projects slightly beyond the ends of thecasing 3 and whichvis provided-at its rear end with a projecting annularfiange 5, that abuts against the end of the'casing 3 and in theperiphery of which is-,form'ed-aseries of notches or recesses 6. Througha slot in the upper' surface or top 2 is fitted a lever 7 and on saidlever, near its upper end, is fulcrumed a transverse lever 8, one end ofwhich is connected to a casing 9 fitted to slide on the flange 5 of thecylinder 4. The casing 9 is, preferably, fitted on the carrier 4 bymeans of lips 9', formed integral with the sides of said casing, whichflanges or lips take over kthe inner edge of the flange 5 and enable thecarrier to be revolved without moving the casing 9, if desired. Withinsaid casing 9 is arranged a dog or detent 10 which fits in a suitableway or groove in the case 9 and which is adapted to beprojected into oneof the notches 6, in the flange of the carrier 4,

by a coiled pressure spring l0 arranged with'- in the 0asing9 below thedog therein.

The cylindrical-carrier 4 is arranged to be locked rigidly in anydesired position by means of a locking detent 1l fulcrumed be-y tweensuitable lugs attached to the fixed casing 3 and provided at one endwith a laterally projecting finger or stud 12 adapted to take into oneof the peripheral notches 6 in the flange 5 of the cylindrical carrier.The cylindrical carrier is kept stationary-or fixed by a flat spring 13attached at one end to the casing 3 and bearing, at its free end,against the underside of the locking detent 11, below the fulcrumthereof, to keep the finger or stud 12, in one of the notches 6. Thefree-end of the lever S is bent at right angles to its length andextends across the lower portion vof the locking detent 1-1 and when thelever 7 is oscillated, by any suitable means, the casing 9 `will bemoved onv the flange 5 and the dog,

l0, therein, will take into one of the peripheral notches 6 and operateto turn the cylindrical carrier one step or notch, the finger or stud l2being elevated out of engagement with the fiange 5 by pressure of thehook portion of the lever 8 on the lower end thereof. When the lever 7has reached the limit of its forward movement and starts back to itsoriginal position, the casing 9 will be moved on the flange 5, the dog10 having its upper surface inclined to permit of such rearwardmovement; and, asl soon as pressure is removed from the lower end of thedetent 1l such lever will be returned to its normal p0- sition and thestud or finger 12 forced into one of the notches 6 by the action of thespring 13.

Through the cylindrical carrier4 extends a series of spindles 14, 15,16, 17 and 18, and these spindles project slightly beyond the ends ofthe cylindrical carrier. On` each of these spindles is fitted a collar19, which is held in position on the spindle by means of a set screw 19.A finger 20, formed integral with each collar 19, extends through one ofa series of longitudinal slots 21 formed in a tube 21 which is rigidlyattached to the rear end or head of the cylindrical carrier 4. The outerend of the tube 2l is closed by a plug .312 and within said tube, inadvance of the lingers 20, is arranged acoilcd spring 22,and betweensaid fingers and the rearend of the coiled spring 22 is situated a block22so that as either of the` spindles is moved forward, by means to behereinafter pointed out, the spring 22 will becompressed, and whenpressure isremovedfrom the rear end of said spindle the spring 22willreturn the spindle to its normal position.

In a suitablesocket formed in the outer end of the spindle 14, is fitteda cutter 23 which is held firmly in place by means of a set screw 23.This cutter is adapted to form in one1 end of a wire 24 a socket orrecess adapted to receivea jewehsaid `wire 24 being rotated and.`carried by alathe inthe ordinary manner.

The forward solid` end of the spindle 15 is conical or tapered as shown,and said spindle is adapted, when the cylindricalcarrier is turned totbring themsame in line.` with thepro- .jecting end of the wire 24,r andit is moved forward by means totbe hereinafterdescribed, to force ajewel carried by a suitable holder, into the socket or recess previouslyformed by the cutter 23 inthe end of the; wire 24.

In the forward end or head of the spindle 16, (which head isenlarged)isformed: a groove or way 25 in` which is fitted a movable block 25.` Theblock 25' is held in position in the groove or way formed in the head ofthe spindlereferred to, by a screw 26, which is screwed into such` headand has its enlarged head extending into agrooveor recess formed in therear side of the movable block 25. A` burnisher 26 is fitted in asocketformed in the 4outer face of the block 25' and is held firmly in` suchsocket by a set screw 27. The burnisher is preferably made in` they formshown in Fig. 7, in which it consists of a blunt cen- `tral springpressedpin 27 and acutting or `burnishing edge or point 23 arrangedslightly in rear of the blunt pointof thepin 27 and extending at anacute angle to` the length of said pin. When the spindle 16 is broughtlin line with the Wire 24, and isprojected forward, the blu-nt end of thepin 27 bears against the center of the jewel which has been previouslysecured in the socket, formed in the end of the wire by the cutter 23 onthe spindle l5, and keeps the jewel in place in the cured anothercutter, preferably by having its ystem or shank seated in a socketformed in 'the end of said spindle.

This cutter of the spindle 17, consists, as shown in Figs. 8 and 9, of abody 29 provided with an integral stem or shank 29" designed to beinserted into a suitable socket formed in the forward end of the spindle17. On the upper side of the body 29 is centrally pivoted a circularcutting blade 30, provided with a series of peripheral teeth 30. Thecentral pivot of the blade 30 extends through a slot inthebody 29 and onsaid pivot pin, near the lower end thereof, is rigidly secured a ratchetwheel 31. Below the wheel 31 is fulcrumed a bell crank lever 32, theshorter annil 32 of which is connected with the. front end or headof thecylindrical carrier 4 by a coiled spring 33. To the body 29, in rear oftheshort arm of thelever 32, is secured a` downwardly projecting pin orstud 33 adapted to4 limit the play or movement of the bellcrank inone-direction. To the front end or head of the cylindrical carrier isattached a projecting pin 34 arranged in the path of the long arm of thebell crank., When-thespiudle 17 has been brought into-line with the Wire24 and` projected forward the required distance, thecu-tting blade 30will operaterto remove from the end of the wire the` surplus materialIwhich has been raised up or formed by the action of the burnishercarried by the spindle 1G. As the spindle 17 is withdrawn to its normalposition, the longer arm of thebell crank 32 comes in contact with thefixed pin 34 and as the spindle moves rearwardly the said arm of thelever 32 Wil-l be forced forward and a pawl or dog 34 thereon takes intothe teeth of the `ratchet wheel4 31 and turns the same, thus bringinginto operative position another tooth on the cutting blade 30. When thespindle 17, is moved forward agaiintlie coiled spring 33 operatestoreturn the lever to its normal position.

The head or forward end of the spindle 18 is similar tothe head of thespindle 16; and

is provided with a movable block 35. A

trimming blade 36 is held in place in a socket formed in the movableblock 35 by means of a. set screw 36. The blade 36 operates when broughtto bear against the end of the wire 24 to trim or reduce such wire tothe desired size to form the setting of the jewel.

. At the` forward end or head of the cylindrical carrier 4, betweenthespindles 14, 18, is arranged a stationary stud 37 provided atits `outerfree end with an` internally threaded socket in which is fitted a screw37. The endof the wire 24 abuts against the screw 37 and said screw canbe adjustedto vary the length of said wire from the lathe.

3S designates a lever which Works through a longitudinal slot in the topof the table 2.

On said lever, near the upper endthereof, is pivotally mounted a pushingnger38 provided in its forward free end with a socket which, when thelever 3S is oscillated, by suitable mechanism, and the upper end thereofmoved forward, receives the rear end of one of the series of spindles14,' 15, 16, 17,l 18. The spindle-which is in line with the pushingfinger 38 is moved forward as such linger advances, and the implementcarriedv by said spindle is brought into proper position for operation.When the upper end ofy the lever- 38 moves `rearwardly the spindle withwhich it is in contact is also returned to its normal position by theaction ofthe spring 22.

Over the rear ends of the spindles 16 and 17, carrying the burnisher 26and-cutter 30, respectively, are fitted sleeves 39 which are closed attheir rear ends and held in placev on the spindles by screws 40 whichextend' through longitudinal slots formed in said sleeves. Within thesleeves 39, between'the closed rear ends thereof and the ends of the'spindles, are arranged coiled cushion springs 39. The object of thisconstruction is to prevent the burnisher or the cutter from beingpressed against the jewelwith sufficient force to damage or injure thesame.

In the rear ends of all of thelongitudinally movable spindles mounted inthe carrier 4, I preferably secure a screw .40, the head of' which is ofsuch size as to fit snugly in the socket in the forward end of thepushing finger 38 andsaid screws can be adjusted to lengthen or shortensaid "'spindles.

To the fixed casing/3, at the forward end thereof, is rigidly'secured abracket 4l and v through asuitable aperture formedv in the upwardlyextending arm of said bracket is passed a pivot lug or 'stud 42 ofan'arm 43'. In the rear face of the arm 43, below the pivot pointthereof, is formed a longitudinal guide way in which is fitted a yjewelcarryingslide 44,l which is held in position within the guide way in thearm'43 by a pin 45. In the inner face of the slide 44 is formed a grooveor channel 44 designed to receive a number of jewels of the proper sizeto lit in the socket which is formed in the end of the wire 24 by thecutter 23; and 4the lower end of this groove or channel communicateswith a transverse channel or groove formed in the front face of the arm43. This latter channel is of greater di-A ameter at its upper than atits lower end and init is fitted a block or slide 45' which is held inplace by a'iiat spring arm 46 secured at one end to the arm 43 andextending across the upper end'of said block 45.

To the outer face of the slide 44 is attached a short outwardlyprojecting sleeve 46', the inner end of which communicates with thelongitudinal channel 44 in rearof thejslide 44; and in said sleeve 46 isfitted a pin47- provided with an enlarged head. On the pin' 47, betweenthe head thereof and the end of the sleeve 46', is formed an annularflange 47.`

The p in 47 is normally held out of the channel 44 by means of a flatspring arm 4S which is attached at one end to the outerface of the slide44 and has itsfree Vend bifu'rcated and extending on opposite sides ofthe pin 47, be-

tween the enlarged head thereof and the annula'r flange 47. In the upperend of the longitudinal guide way in the arm 43, and bearing against theupper end of the slide 44, is'arranged a coiled spring 4S.

In advance and at one side of the axially turning vcarrier 4 and thesupporting fixed loasing3 thereof, is arranged another lever 49 whichisfulcrumed between lugs 49 secured on the top of the table 2, and saidlever extends down through a short transverse slot formed insuch top. Tothe upper end of the lever 49 is attached a finger 50 which Vextendsupwardly and laterally from the lever 49'and has its outer endbifurcated. In suchI bifurcated end is journaleda roller 5l providedwith a peripheral groove in which the lower edge of the arm 43 fits. Thearm 43 is kept pressed against the rollerl 51 by means of a spring 52which is `coiled around the pivot stud`42 and has one end extendingacross the' upwardly extending arm of the bracket 4l on the fixed casingl3 and its other` end extending across the upper side or edge of the arm43 above the pivotal point of the same. The spring 52 serves to keep theupper end of the varm,-'43, elevated and the jewels carried by the slide44 near the lower forward end thereof.

Below the top of the table 2 is preferably arranged a longitudinalsha-ft 53, which is journaled in suitable bearings and provided withsuitable driving means, not shown. On the shaft 53 are rigidly securedthree disks 54, 55, 56. In one face of. the disk 55is formed a camgroove having as many offsets as there are notches in the liange 5 atthe'rear end of the cylindrical carrier 4, and in said groove rides aguide roller attached to the lever 7 and which, as the shaft 53 isrotated, causes the Vlever 7 to oscillate and rotate the carrier with astep by step motion to bring the different implements carried by thespindle suc cessively in line with the projecting end of the wire 24.The other disk 54 on' the driving shaft is also provided in one facewith a cam groove in which rides a roller attached to the lever 49 tooscillate the same as the shaft-53 is rotated and thus alternately raisethe rear upper end of the arm 43.l The remaining-disk 56 is providedwith a' proper cam surface against which the lower end of the lever 38bears and as the shaft 53-is .rotated the lever 3S is scillated and thespindle in line with the finger`38 is moved yforward to bring theimplement carried atv its forward end into operative position.

A spring,382, is arranged below the top of the support, 2, and one endof saidv spring is attached to the rear wall of said support 'and theother end to the level-,38, above the fulcrum thereof.v

The operation of my invention is as fol- IIO lows: The wire 24, or thematerial from which it is desired to form the jewel settings, and whichis carried and adapted to be revolved by a suitable lathe in theordinary manner, is advanced until the free end thereof cornes incontact with the end of the fixed stationary stud 37. The shaft 53 isthen slowly revolved and as the lever 7 moves forward, the dog or detent10 takes into one of the notches 6 and turns the cylinder one step tobring the spindle 14 in line with the wire 24. As the spindle 14 reachesits proper position, the lever 7 moves back to its normal position andthe casing 9, attached to such lever, moves on the flange 5, theinclined upper end of the dog 10 permitting the same to free itself fromthe notch 6; and the lever 38 is moved forward. As the lever 38 movesforward, the rear end of the spindle 14 enters the socket in the freeend of the finger 38 and said spindle is moved endwise until the cuttercarried at the forward end thereof contacts with the end of therevolving wire 24 and speedily forms therein a socket of properdimensions and form to receive a jewel. As the lever 7 starts forwardagain to rotate the carrier 4 another notch or step, the lever 3S andspindle 14 regain their normal positions by action of the springs 382and 22, respectively, and the spindle 15 is brought into line with thewire 24. As the carrier is turning to bring the spindle 15 intooperative position, the lever 49 is moved and the upper end ofthe arm 43elevated. As the upper end of the arm 43 is raised, the lower end ofsaid arm is depressed and the projecting end of the wire 24 contactswith and moves the block 45 longitudinally to expose the lower portionof the groove or way in which it is fitted and the lower end of thelongitudinal jewel receiving channel 44. As the block 45 is raised tothus expose the jewel receiving channel 44, the spindle 15 is movedforward by the lever 38 and the outer end of said spindle bears againstthe enlarged head of the pin 47 and forces said pin forward. The forwardmotion of the pin 47 forces a jewel from the channel 44 into the socket,previously formed in the end of the wire 24 by the cutter 23. As thelever 49 returns to its normal position, the upper end of the arm 43 isdepressed by the action of the spring 52 and as the lower end thereofmoves upwardly the block or slide 45 is returned to its normal positionby the spring arm 46, the pin 47 having been withdrawn, as soon as thespindle 15 has been moved rearwardly out of contact therewith, by thespring arm 43. The

- carrier 4 is then rotated to bring the different able the channel 44therein to be fitted with jewels, by withdrawing the pin 45.

From the foregoing description and dra-wings it will be seen that I haveprovided a simple, and compact machine for automatically preparing thejewel setting, securing the jewel in place therein, and finishing thesetting.

I am aware that changes in the form and proportion of parts and detailsof construc-` tion of the devices herein shown and described as anembodiment of my invention can be made without departing fromthe spiritor sacrificing the advantages thereof. For instance although I havedescribed one form of mechanism adapted to operate my machine from acommon driving shaft, yetI am aware that many other forms can besubstituted with equally good results, and I do not therefore wish to beunderstood as intending to limit myself to the specific construction andarrangement of parts herein shown and described.
